如何使用Java Prepared语句在sqlserver的datetime字段中设置日期和时间

Question

I am receiving time in milliseconds and I would like to convert that into date and time format and store that value in datetime column in sqlserver .

Following is the code which is working and converting milliseconds to date and time but it is unable to set the date and time value in database column.

    String datetime = 1488288835716
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(Long.parseLong(datetime));
    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
    String datestring= formatter.format(calendar.getTime());
    UpdateStatement.setString(1,datestring)

Answer 1

You don't need to convert the given milliseconds into any textual representation. In fact most databases store time / datetime values in milliseconds anyway.

Instead, use java.sql.Timestamp like this:

long timeInMillis = 1488288835716;
Timestamp time = new Timestamp(timeInMillis);
updateStatement.setTimestamp(1, time);

Answer 2

Can you try this, to overcome possible issues with locale, culture and so on?

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

I am not proficient in Java, but this can be a problem with SQL Server, so I always put date strings in this format before writing to the database.
